The Senate report into the CIA’s secret torture programmes is clinical and unsparing.

Over the course of a 480-page summary, it lays out in horrifying detail what was done to detainees in secret torture sites around the world. Here are some of the starkest examples:

Detainees were “rectally fed”

At least five prisoners were forced to ingest food or water through their rectums. One detainee, Majid Khan, went on hunger strike and had a “food tray” of pureed hummus, pasta, nuts and raisins forced into his rectum. Khan apparently tried to kill himself by biting his own veins.

In 2012, he pleaded guilty to terror charges in front of a military court at Guantánamo Bay.

Prisoner dies of suspected hypothermia

In November 2002, the suspected Afghan militant Gul Rahman was being held at “the Salt Pit”, a secret US prison in Afghanistan. Rahman was stripped naked below the waist, chained, and made to sit on a bare concrete floor. He was found dead the next day of suspected hypothermia.

26 of 119 prisoners were wrongfully held

Among the people who were wrongly held was Nazar Ali, “an ‘intellectually challenged’ individual whose taped crying was used as leverage against his family member”.
